ArcGIS Online - Calculate Field Automatically

BenGrod

When editing an ArcGIS Online hosted feature layer within a web map or web app is there a way to automatically calculate a field upon creation of the feature? I am trying to automatically calculate the area (square feet) of a polygon after it is created.

Ben, this is not possible.

Shouldn't there be a SHAPE.AREA field within your feature service?

BenGrod

Yes, but the coordinate system is WGS 84 and the shape.area is square meters. I actually need to populate the square feet field which is a simple calculation but I would like to do it automatically.

Yeah, I was afraid of that. Thank you though Tim!

i am searching for the same functionnality.

Possible programmatically in the front office without using esri tech. (i use jsp,javascript to pass sql transactions to the database)

Possible by creating trigger in the database.

but on the cloud i don't know.

Anyone here in 2021 please upvote idea supporting Attribute Rules in ArcGIS Online to enable this.
